Database Connection Error - Need Help

Question

I have a Crystal Reports report that "stopped working".  When I preview the report, I receive a Database Connection error.  I have a copy of the error posted at http://www.foreigncandy.com/crystalreportserror.jpg.
Anyone have any ideas what's causing this?  We are new to SAP and Crystal Reports.
Thanks

I'm not sure what database version you are looking for.  it's Crystal Reports 2008 version 12.
Could it be a a problem with the setup of an item?
Here's the SQL query:
-- Create temporary table variable
DECLARE @LineQuantities TABLE
     DocEntry int,
     DocDate datetime,
     ItemCode varchar(20),
     Quantity numeric(19,6),

     Last12WeekSales numeric(19,6),
     Week1Sales numeric(19,6),
     Week2Sales numeric(19,6),
     Week3Sales numeric(19,6),
     Week4Sales numeric(19,6),
     Week5Sales numeric(19,6),
     Week6Sales numeric(19,6),
     Week7Sales numeric(19,6),
     Week8Sales numeric(19,6),
     Week9Sales numeric(19,6),
     Week10Sales numeric(19,6),
     Week11Sales numeric(19,6),
     Week12Sales numeric(19,6)
